IMPROVELEENT IN SOLDERINGMACHINES.

The Schedule referred to in these Lettere: Patent and making part efl the same.

and to the letters of reference marked thereon. A

V'The object of this invention is to construct a machine for holding the several pieces or sheets of tin, or other metal of which a water-gutter or eaves-trough is composed, in the proper position for soldering, and in a straight line.

We are well aware that other -machines are now in use for the same purpose, but that, being imperfectly ,adapted to the business,'they are almost entirely worthless. y

These. other machines, to which we allude, have usually convex bed-pieces, to which the concave sides of the metal sheets are secured by means of springhasps.

In this manner the gutter is formed bottom side up, and in this position the completed gutter is so yielding and ilexble, that it is impossible to construct anything but very short sections of gutter at one operation, owing to the deflection of the overhanging ends thereof.

Guttering constructedin this manner is open to the still further objection that its joints are soldered only on the outside, and for this reason it isoften found impossible to discover aud repair leaky j oints without removing. the gutter from the building.

It is to'remedy the-defects of this kind in existing machines, that the present machine is provided.

Briefly, it consists of a hollow trough, in which the various sections or sheets of metal intended to form a gutter are placed,` and held, by means of spring-clamps,

in such positionsas'to 'besoldered to one another, as required. The 'said'trough, by being hung on trunnions, may be turned to eitherside, so as to always solder on the bottom' place ofthe seam.-

To enable those skilled in the art to make and use our improved soldering-machine, we will proceed to describe its construction and operation.

Figure I, of the drawings, is an end elevation of the improved machine.

Figure 2 is a plan of the same.

The concave trough A has trunnions c on its ends, which rest on the posts or standards B, that' are erected on the platform B.

'This trough should be long enough to hold three or four (more or less) sheets or pieces C Cl Oz, in the proper positions for forming a water-gutter.

Spring-clamps, D D D2 D3, are secured to the sides of the trough, and arranged to fold down into the trough in' pairs, and their ends turning over at d, in scrolls, will s o spring together, as is shown in iig. 2, as to hold the said sheets down tightly to the trough until their joints c are soldered.

The first two pairs cf these clamps, D D, should be placed the proper distance apart vto allow both of the said pairs of clamps to fall 'on the same piece or sheet C, while the remaining distances between D, and D2, and Dsare just sufficient to allow one of the said clamps to fall on one of the additional pieces C* C?.

When a section Vof the gutter formed in this manner has been fully soldered, the clamps may be loosened, and the completed piece shoved along toward the end of the trough, when new sheets will be insertedin the trough, clamped, and soldered as before.v

In this way a long gutter may be formed, without the danger of the overhanging end sagging so as to misshape the piece.

The curled edge c may be placed on either side, so as to make the gutter dip in either direction, without running the water against the joints--a valuable feature ofthe invention, whichcannot be attained in any machine uowgin use, owing to the inequality of the distances between the clamps D Dl D'l D3, as above described.

- By hanging the trough A- on trunnions a, it maybe turned to either side by the operator, so as to solder at the bottom of the groove at all timesa position for soldering, of manifest advantage, owing to the fluid condition of the solder.

The pins a', projecting from the ends of the trough, will'strikethe posts B, so as to prevent the trough from tipping overtoo far.

By usingthe trough A as above described, the crossstays may be inserted in and secured to the gutter, at the time of manufacturing the same.

Having described our invention,

' What we claim, is-

The trough A, supported by tmunious a and thestops a', and in combination with the clamps D Il)l D2 D3. substantially as andior the purpose set forth.

In testimony of -which invention, we hereunto set our hands, in presence of VALENTINE FA'IH. PHILIP FATH. J ULIUS FRIELINGSDORF.
